-  // single number, e.g. in English "2 hours ago".  Currently, all combinations
-  // of format and length except (FORMAT_ELAPSED, LENGTH_LONG) are implemented
-  // but it's easy to add this, if required.

-  // Return a localized string of more precise time duration, either formatted
-  // as a single value or as two values: for a time delta of e.g. 2h19m either
-  // "2 hours" or "2 hours and 19 minutes" could be returned in English.
-  // Two-value output can be forced by setting |cutoff| to -1.  Single-value
-  // output can be forced by using Simple() or setting |cutoff| to 0.
-  // Otherwise, choice of format happens automatically and the value of |cutoff|
-  // determines the largest numeric value that may appear in a single-value
-  // format -- for lower numeric values, a second unit is added to increase
-  // precision.  (Applied to the examples above, a |cutoff| of 2 or smaller
-  // would yield the first string and a |cutoff| of 3 or larger would return the
-  // second string.)
-  //
-  // The aim of this logic is to reduce rounding errors (that in single-value
-  // representation can amount up to 33% of the true time duration) while at the
-  // same time avoiding over-precise time outputs such as e.g. "56 minutes 29
-  // seconds".  The relative rounding error is guaranteed to be less than 0.5 /
-  // |cutoff| (e.g. 5% for a |cutoff| of 10) and a second unit is only used when
-  // necessary to achieve the precision guarantee.
-  //
-  // Currently, the only combination of format and length that is implemented is
-  // (FORMAT_DURATION, LENGTH_LONG), but it's easy to add others if required.
-  //
-  // Note: To allow pre-, post- and infixes which can be inflected depending on
-  // either the first or the second value, two separate translation strings
-  // (IDS_TIME_*_1ST and IDS_TIME_*_2ND) are used per [plurality] times [pair of
-  // units] and are concatenated after having been formatted individually.  The
-  // separator between first unit and second unit (a blank in English) is
-  // included in IDS_TIME_*_1ST.
